La Fortaleza de la Cabaña tenía forma de cuadrado. En cada vértice hay un torreón y en sus cuatro muros baluartes separados 20 metros unos de otros. Si la Fortaleza tiene 100 baluartes, ¿cuál es su perímetro? The Fortress of the Cabin was shaped like a square. At each vertex there is a tower and on its four walls, bastions 20 meters apart from each other. If the Fortress has 100 bastions, what is its perimeter?

Given: ac and db are diameters. m∠3=

Consider the table below. x y -1 -5 0 5 1 11 2 13 3 11 complete the standard form equation representing the quadratic relationship displayed above, where a, b, and c are constants.

Kayla wants to find the width, ab, of a river. she walks along the edge of the river 65 ft and marks point c. then she walks 25 ft further and marks point d. she turns 90° and walks until her location, point a, and point c are collinear. she marks point e at this location, as shown. (a) can kayla conclude that δ and δ are similar? why or why not? (b) suppose de = 15 ft. what can kayla conclude about the width of the river?
